Allagash Wild and Scenic River defines the southeastern corner of this Piscataquis County landscape, where the waters of Eagle Lake meet a dense network of forest drainage systems. The terrain is characterized by complex hydrography, notably the convergence of the West Branch, Middle Branch, North Branch, and East Branch Thoroughfare Brook. These waterways consolidate into the main Thoroughfare Brook, which meanders through the central woodlands. To the southwest, Lower Russell Pond feeds the South Branch and North Branch Russell Brook, illustrating the interconnected nature of the Maine North Woods.
